Repairs, recoats and new spray foam roofs for Glendale homes and small commercial buildings, handled by a licensed Arizona roofing contractor. Here is what is specific to Glendale: the housing stock, the permit rule and the numbers.
Housing stock: Glendale's 1950s–70s core (south of Northern, around Grand Avenue) has flat-roof ranches; the rest of Glendale and the West Valley is tile, which is why foam search in the West Valley is thin. This is our only West Valley page.
Permits: The City of Glendale requires a permit for re-roofing; recoat and repair are maintenance.
Housing-stock notes come from Maricopa County Assessor build years; confirm your own parcel.
Foam roofs fail the same way everywhere in the Valley — the top coat chalks, UV reaches the foam, pinholes and bird holes let the first monsoon storm in — but the timing depends on when the roof went on. Use the calculator to see where yours sits, then call before the next storm rather than after it.
Valley foam roofers publish recoat intervals from 5 years (Durafoam) to 5–7 (Travek) to 8–12 (Arizona Roof Co). We show the two shorter schedules because Phoenix UV is the worst case.
Don't know the install year? The Maricopa County Assessor shows the home's build year; a roofing permit on file with your city gives the re-roof year.
Glendale is quoted at the same published Valley rates as Phoenix; there is no suburb premium for foam, but access (two-story, parapets, HVAC on the roof) moves a quote within the band.

Repair details →Power-wash, repair, prime, new elastomeric or silicone top coat. The job that keeps a foam roof alive for decades.
Recoat details →Over an existing flat roof or after tear-off. Permit required for replacement in Glendale.
New roof details →Published Valley rates are $2–$4 per square foot (Travek), so a typical 1,800–2,200 sq ft flat roof runs about $4,000–$8,000. Access, parapet height and how much repair is needed first move a quote within that band.
The City of Glendale requires a permit for re-roofing; recoat and repair are maintenance.
Valley foam roofers publish 5 years (Durafoam), 5–7 years (Travek) and 8–12 years (Arizona Roof Co). The honest answer is: when the chalk test says so, which in full Phoenix sun is usually the shorter end.
Those areas are almost entirely tile and we don't publish pages for them; if you have a flat roof there, call — the contractor will say whether it's inside their service area.
